Performance parameters
Direction of magnetization along the height (the last dimension included in a magnet name) means that the surface of a magnet perpendicular to its height makes the N-pole, while the other surface perpendicular to the height refers to the S-pole;.
The magnetic force value given above, expressed in kilograms, was measured under ideal conditions. A thick iron plate with a smooth, unpainted surface was used. The force required to detach the magnet from the plate was perpendicular to the plate.
For flat magnets and magnets mounted in the open magnetic circuit working temperature may be insignificantly lower. For high magnets and magnets mounted in the closed magnetic circuit working temperature equals max. working temperature for a given material. Curie’s temperature is ~ 860°[C]. Temperature coefficient of remanence TK(Br): ≤ -0,02 [%/°C]. Temperature coefficient of coercivity TK(HcJ): ≥ +0,02 [%/°C].
AlNiCo Magnets may be used in water.
The magnet parameter values presented here are the result of measurements taken on one specific magnet and are used to compare magnets available in the online shop. We recommend testing the magnet yourself under the expected operating conditions.

This magnet is circular, cylindrical, shaped like a cylinder or disc.
It is an AlNiCo magnet, magnetised along the height. It has two poles, which means it is double-sided.
These magnets are naturally resistant to corrosion, which is a great advantage. They are manufactured to excellent dimensional tolerances.
AlNiCo magnets have a record high operating temperature of no more than 525 degrees Celsius. AlNiCo magnets stick to metal surfaces.
The magnet can be attached to surfaces made of ferromagnetic materials.
